Package nz.org.riskscape.picocli
Interface CommandLine.IHelpCommandInitializable
- All Known Implementing Classes:
CommandLine.HelpCommand
- Enclosing class:
- CommandLine
Deprecated.
Help commands that provide usage help for other commands can implement this interface to be initialized with the information they need.
The CommandLine::printHelpIfRequested
method calls the
init
method on commands marked as helpCommand
before the help command's run
or call
method is called.
Implementation note:
If an error occurs in the run
or call
method while processing the help request, it is recommended custom Help
commands throw a ParameterException
with a reference to the parent command. The DefaultExceptionHandler
will print
the error message and the usage for the parent command, and will terminate with the exit code of the exception handler if one was set.
